one thing that worked for me was to impose a hour waiting period on anything i want to buy unless its truly minor like a coffee and a bagel almost without exception the techy thing i thought i could really really use and would be a great purchase one day seemed unnecessary and superfluous the next if hours doesnt work for you try or it eliminates the visceral impulse buying addiction if youre disciplined enough to stick to it for a couple of months buying crap releases endorphins buyers remorse is biologically similar to the regretshame you feel after jerking off to tranny porn
